Instance Public methods
Creates new flash types. You can pass as many types as you want to create flash types other than the default
notice in your controllers and views. For instance:
# in application_controller.rb class ApplicationController < ActionController::Base add_flash_types :warning end # in your controller redirect_to user_path(@user), warning: "Incomplete profile" # in your view <%= warning %>
This method will automatically define a new method for each of the given names, and it will be available in your views.
